Abstract: Data traffic is scheduled by, in a first scheduler, selecting a source of traffic from a plurality of sources of traffic, each source being associated with a second scheduler, in a second scheduler associated with the selected source of traffic, selecting a type of traffic from a plurality of types of traffic within the source selected by the first scheduler, and transmitting data of the selected type and source. Identifying and creating tunnels between endpoints in a network for optimum data traffic method and apparatus.

Abstract: A communication device integrates traffic monitoring, policy configuration and enforcement, and proxy services within the device. The policies can affect both prioritization of data as well as allocation of communication bandwidth. Data packets that are accepted at the device are classified according to a set of defined classes and are transmitted through the device according to a policy for prioritization and bandwidth allocation for the classes. Optionally, some of the packets are passed to a proxy application hosted in the communication device. The device functions as a link-layer bridge, thereby allowing the device to be inserted into a data path without reconfiguring network layer software at devices that use that data path. The device includes operating modes in which packets are passed through the device without modification.

Abstract: The present invention is a method and apparatus to segment a three-dimensional scene having foreground and background regions. Regions in stereo images of the 3-D scene are matched. The stereo images include left and right images. Ranges of matched regions are computed. The foreground region is separated from the background region using the computed ranges of the matched regions.

Abstract: A system for transparent recovery from a communications disruption during transmission of a data stream from a source computer to a destination computer is implemented in a method including the steps of determining a portion of the data stream that was successfully received by the destination computer and resuming the transmission from a point in the data stream immediately after the successfully received portion.

Abstract: A method and an apparatus for scaling E-mail (electronic mail) address book databases for devices with limited storage capacity and synchronization of a first set of mail with a second set of mail at the message/folder level. A memory contains a mail subsetter for automatically generating a default personal address book and a mail synchronizer for application independent E-mail synchronization. A pseudo unique identification is generated for each message or folder in the mail boxes to be synchronized. An event log is then generated for each mail box. The memory also has a Synchronization mechanism for making the first set of data and the second set of data equivalent by using the information in the Change List generated by the Change Detection Mechanism. A processor runs the mail synchronizer.
